Art Skill

Complete visual content system for creating illustrations, diagrams, and visual content.

Customization

Before executing, check for user customizations at: ~/.claude/skills/CORE/USER/SKILLCUSTOMIZATIONS/Art/

If this directory exists, load and apply:

• PREFERENCES.md - Aesthetic preferences, default model, output location
• CharacterSpecs.md - Character design specifications
• SceneConstruction.md - Scene composition guidelines

These override default behavior. If the directory does not exist, proceed with skill defaults.

🚨🚨🚨 MANDATORY: Output to Downloads First 🚨🚨🚨

1. Send voice notification:

   Copycurl -s -X POST http://localhost:8888/notify \
     -H "Content-Type: application/json" \
     -d '{"message": "Running the WORKFLOWNAME workflow from the Art skill"}' \
     > /dev/null 2>&1 &
   

2. Output text notification:

Core Aesthetic

Default: Production-quality concept art style appropriate for editorial and technical content.

User customization defines specific aesthetic preferences including:

• Visual style and influences
• Line treatment and rendering approach
• Color palette and wash technique
• Character design specifications
• Scene composition rules

Load from: ~/.claude/skills/CORE/USER/SKILLCUSTOMIZATIONS/Art/PREFERENCES.md

---

Reference Images

User customization may include reference images for consistent style.

Check ~/.claude/skills/CORE/USER/SKILLCUSTOMIZATIONS/Art/PREFERENCES.md for:

• Reference image locations
• Style examples by use case
• Character and scene reference guidance

Usage: Before generating images, load relevant user-provided references to match their preferred style.

---

Image Generation

Default model: Check user customization at SKILLCUSTOMIZATIONS/Art/PREFERENCES.md Fallback: nano-banana-pro (Gemini 3 Pro)

🚨 CRITICAL: Always Output to Downloads First

ALL generated images MUST go to ~/Downloads/ first for preview and selection.

Never output directly to a project's public/images/ directory. User needs to review images in Preview before they're used.

Workflow:

1. Generate to ~/Downloads/[descriptive-name].png
2. User reviews in Preview
3. If approved, THEN copy to final destination (e.g., cms/public/images/)
4. Create WebP and thumbnail versions at final destination

Copy# CORRECT - Output to Downloads for preview
bun run ~/.claude/skills/Art/Tools/Generate.ts \
  --model nano-banana-pro \
  --prompt "[PROMPT]" \
  --size 2K \
  --aspect-ratio 1:1 \
  --thumbnail \
  --output ~/Downloads/blog-header-concept.png

# After approval, copy to final location
cp ~/Downloads/blog-header-concept.png ~/Projects/Website/cms/public/images/
cp ~/Downloads/blog-header-concept-thumb.png ~/Projects/Website/cms/public/images/

Multiple Reference Images (Character/Style Consistency)

For improved character or style consistency, use multiple --reference-image flags:

Copy# Multiple reference images for better likeness
bun run ~/.claude/skills/Art/Tools/Generate.ts \
  --model nano-banana-pro \
  --prompt "Person from references at a party..." \
  --reference-image face1.jpg \
  --reference-image face2.jpg \
  --reference-image face3.jpg \
  --size 2K \
  --aspect-ratio 16:9 \
  --output ~/Downloads/character-scene.png

API Limits (Gemini):

• Up to 5 human reference images
• Up to 6 object reference images
• Maximum 14 total reference images per request

API keys in: ${PAI_DIR}/.env
